正好前一阵看了这么一个新闻,17年底的事儿,尽管不能直接回答这个问题,不过...

That Game on Your Phone May Be Tracking What You're Watching on TV
Yet these apps, once downloaded onto a smartphone, have the ability to keep tabs on the viewing habits of their users — some of whom may be children — even when the games aren't being played.
It is yet another example of how companies, using devices that many people feel they can't do without, are documenting how audiences in a rapidly changing entertainment landscape are viewing television and commercials.
The apps use software from Alphonso, a start-up that collects TV-viewing data for advertisers. Using a smartphone's microphone, Alphonso's software can detail what people watch by identifying audio signals in TV ads and shows, sometimes even matching that information with the places people visit and the movies they see. The information can then be used to target ads more precisely and to try to analyze things like which ads prompted a person to go to a car dealership.
More than 250 games that use Alphonso software are available in the Google Play store; some are also available in Apple's app store.
大体就是说Alphonso是一家为广告商提供电视节目观看数据的企业,广告商可以通过用户的电视节目观看习惯来更好地推送广告
那么它是怎么收集这些数据的呢...
通过用户的手机话筒来检测电视里面的声音
那么它是怎么跑到用户手机上去的呢
内置在游戏里,而且谷歌商店上已经有超过250个游戏内置了Alphonso的软件...
当然这家公司宣称不会收集手机用户的对话信息,也拒绝公布到底收集了多少数据,只是说用户可以自己选择关掉访问话筒的权限
要放了以前我觉得手机软件实时监听用户对话,有点儿阴谋论的感觉...
现在可以完全确认的是
通过话筒监听对话技术上没有难度
已经有别的公司确实这么做了,而且还是正规的企业,而且(貌似)还没因此受到处罚,而且还会继续做下去
根据部分答案可以疑似确认的是
手机淘宝在用户没有进行语音输入的时间段使用了话筒
淘宝上推送的商品和用户日常对话有关联性
emmm.....这个趋势太可怕了 |
